Circulation is the flow of blood throughout the body. Beginning at the heart, blood travels through the largest blood vessels and gradually flows down the tiniest of capillaries, where oxygen exchange provides bodily tissues with all of their energy requirements. Hot yoga can serve to improve an individual's circulation when the rising body temperatures cause vasodilation, a bodily adaptation that allows blood vessels to widen and stretch to adjust blood flow to surface areas, lower core temperature, or answer increased energy demand.
Improving vascular tone in this way not only helps keep distal body tissues healthy, but it also improves kidney function, reduces stress, and assists in promoting blood detoxification. Additionally, individuals with certain conditions that limit their circulation, such as Raynaud's disease or peripheral neuropathy, may see extra benefits from hot yoga.
